Wooden lens board 150x150mm with 102mm hole - for Deardorff?

Description

I have for sale here a wood lens board 150 x 150 mm with a 102 mm centered hole. Which translates to 5.9 x 5.9" with a 4" hole.
Lens board is square and measures 150 x 150 mm from side to side or 5 3/4". Total thickness is 11 mm and the thin lip is about 5 mm thick.
It looks to me like this is a 6" Deardorff board:

I charge nothing for packaging materials and no there is no handling costs. These shipping rates are actual rates from national postal services. Yes, they are unreasonably high. But they can be trusted, I never use tracking or insurance myself. But this can be different for other countries and I can of course not guarantee anything.
Import duties, taxes, and other customs charges are not included in the item price or shipping cost. These charges are the buyer's responsibility.
